Railroad ties, collapsed culverts, fire hydrants and steel pipes were among the many unique features and potential hazards identified and marked by approximately 200 Wisconsin Army National Guard Soldiers at the site of the former Badger Army Ammunition Plant near Baraboo, Wisconsin, March 28.The Soldiers were part of the Madison, Wisconsin-based 1st Squadron, 105th Cavalry Regiment. Troop A, from Fort Atkinson, Wisconsin, and Troop B, from Watertown, Wisconsin, were on-hand to assist the Wisconsin Department of Natural Resources with the site survey. The DNR, the Ho-Chunk Nation and the Dairy Forage Research Center all own portions of the sprawling 7,534-acre site, and the site survey took place on the DNR's parcel.
